Definitions

  • the present invention relates to a bearing assembly having an inner ring and an outer ring, which form a bearing between them, according to the preamble of claim 1.
  • lubricant may be present to lubricate the bearing interior, or rolling elements, which may be arranged between the fixed inner ring and the rotating outer ring.
  • rolling elements which may be arranged between the fixed inner ring and the rotating outer ring.
  • the lubricant in the bearing interior is moved in the direction of the 12 o'clock position of the inner race.
  • the inventors have recognized that during rotation of the inner ring or outer ring, the lubricant is moved beyond the 12 o'clock position. Therefore, the lubricant can be carried out through through holes arranged between a 9 o'clock and a 3 o'clock position.
  • the self-adjusting distribution of the lubricant concentration at the periphery of the respective stationary ring is dependent on the bearing geometry and the rotational speed.
  • the diameter of the through-hole may vary over its length, with a minimum diameter of 250 mm 2 being preferred to ensure lubricant delivery.
  • the cross section of the passage opening may have different shapes, for example circular, but also elliptical, oblong or rectangular.
  • a suction device may be provided on at least one of the at least one passage opening.
  • the suction device may serve to assist the drainage of lubricant through the passage openings.
  • the suction device sucks, for example, by means of negative pressure at the through-openings lubricant present.
  • the suction device can be arranged for example in the bearing interior.
  • a reservoir may be directly or indirectly connected to the through-hole.
  • the reservoir may be detachably mounted on the bearing itself or may be provided remotely and connected to the bearing by a hose or other conduit.
  • the reservoir can itself be configured as a solid container or as a hose, which can be flexibly adapted to the bearing, for example.
  • the reservoir is arranged below the passage opening, so that the lubricant can drain into the reservoir.
  • a conduit system may be disposed on the one or more ports to drain the lubricant.
  • the reservoir may be connected to the conduit system into which the spent lubricant is directed.
  • the piping system can consist of a hose that is flexible and easy to adapt to the bearing.
  • the conduit system may also consist of rigid components connected to the passage openings.
  • the reservoir may be detachably mounted on the bearing itself, or may be provided remotely and connected to the bearing or conduit system by a hose or other conduit. The reservoir may be sealed to the conduit system.
  • a suction device may be provided which supports by negative pressure, the flow of lubricant through the through holes 8.
